Definitions
- the invention relates to a fuel distribution apparatus, particularly but not exclusively limited to a fuel distribution apparatus for use in a jet engine.
- Conventional fuel injectors on many jet engines comprise a fuel injector mounted on an outer casing with fuel fed through an internal passage into a gallery that exits a nozzle to mix with swirled air for subsequent ignition. The fuel is merely sprayed into the swirling air.
- WO 000070 discloses a fuel injector for a combustor.
- the fuel is introduced into the injector to provide a swirl to the fuel in a first annular channel which communicates with a coaxial conical fuel swirl chamber and then the primary nozzle.
- a secondary annular swirl channel is provided for spinning the fuel and communicating downstream with a conical fuel swirl chamber and eventually an annular nozzle whereby the fuel is atomized as it exits the nozzle.
- An air swirler is also provided with the fuel injector, and the air swirler includes air passages arranged in an annular array about the fuel injector tip.
- such an arrangement may not provide an even fuel spray in the combustion chamber.
- the change in the swirl angle between the fuel entering the outlet manifold and exiting the manifold to enter the fuel delivery tubes ensures a more even fuel distribution to all of the fuel delivery tubes.
- the fuel delivery tubes extend from the outlet manifold at an angle different to the swirl angle of fuel in the outlet manifold.
- the fuel delivery tubes extend from the outlet manifold in a different direction to the first swirl direction.
- the fuel delivery tubes may extend axially, parallel with the axis of the annular outlet manifold.
- a fuel distribution apparatus comprising a body defining an inlet for receiving fuel, an inlet manifold having a plurality of outlet fluid passageways extending therefrom to an annular outlet manifold, the outlet fluid passageways being arranged to direct fluid into the annular outlet manifold in such a way as to cause the fluid to flow substantially circumferentially of the manifold, the manifold having a plurality of fluid exit ports formed in the radially inner wall thereof to allow fluid in the manifold to exit the manifold.
- the combustion system 10 comprises a casing 14 with a fuel line 16 (shown schematically) running from a fuel supply (not shown) to the fuel distribution apparatus 12.
- the casing 14 has a flat mounting surface 18 formed on the inside surface thereon facing a combustion chamber 20.
- the fuel line 16 terminates and is in fluid communication with fuel inlet channel 22 drilled from the mounting surface 18 into the inner part of the casing 14.
- the mounting surface 18 also has an annular channel 24 machined into the surface, part of which is coincident with the point at which the fuel inlet channel 22 emerges from the body of the casing 14. Furthermore, the mounting surface 18 has a screw-threaded bore 26 formed concentrically with the annular channel 24.
- the fuel distribution apparatus 12 comprises a manifold head 28, a waisted portion 30 and a nozzle head 32.
- the manifold head 28 comprises a stepped cylindrical body 34 having a substantially flat face 36 at one end for arrangement against the mounting surface 18.
- a series of channels and passageways are machined into the surface of the face 36 so that when the face 36 is mounted against the mounting surface 18, those channels form closed fluid passageways.
- a screw-threaded bore 38 is formed centrally of the stepped cylindrical body 34.
- the bore is substantially the same diameter as the screw-threaded bore in the mounting surface 18 and is arranged co-axially therewith when the fuel distribution apparatus 12 is mounted on the mounting surface 18.
- annular inlet manifold channel 40 surrounds the screw threaded bore 38.
- the annular inlet manifold channel 40 has the same diameter as the annular channel 24 formed in the mounting surface 18.
- FIGs 3-7 the channels formed in the mounting surface 18 and the manifold head 28 are shown in negative form. In other words, what is shown in Figures 3-7 are the spaces defined within the fuel distribution apparatus.
- the channels 44 are formed in the flat face 36 of the stepped cylindrical body 34.
- the channels 44 extend from the annular inlet manifold channel 40 substantially tangentially relative thereto.
- the channels are arranged at regular 60° degree intervals around the circumference of the annular inlet manifold channel 40. When closed off by the mounting surface 18 of the casing 14, the channels 44 form outlet fluid passageways 46.
- annular outlet manifold channel 48 is formed concentrically with the annular inlet manifold channel 40 in the flat face 36 of the stepped cylindrical body 34. Again, when the channel 48 is closed off by the mounting surface 18 of the casing 14, the annular outlet manifold channel 48 forms an annular outlet manifold 50. The outer ends of the outlet fluid passageways 46 open into the annular outlet manifold 50. Thus, the annular inlet manifold 42 and the annular outlet manifold 50 are connected together in fluid communication by means of the outlet fluid passageways 46. The openings of the outlet fluid passageways 46 are in the inner wall of the annular outlet manifold 50. Three ports 52 are formed in the inner wall of the annular outlet manifold 50. The ports are regularly angularly spaced at 120° degrees relative to each other. The ports 52 are respectively arranged between pairs of outlet fluid passageways 46.
- the ports 52 act as an entry for respective fluid delivery tubes 54 which extend from the ports 52 at one end thereof in a substantially helical fashion around the waisted portion 30 into the nozzle head 32. This is best shown in Fig.5 .
- helical shall be understood to mean the shape a line would assume if wound around a cylinder or cone.
- the fuel delivery tubes 54 are arranged so that their ends in the nozzle head 32 extend at an approximately 45° degree angle relative to the axis of the device defined by the annular manifolds:
- a bolt (not shown) is screwed into the screw-threaded bore 26 in the mounting surface 18 and the fuel distribution apparatus 12 is screwed on to the protruding bolt so that the bolt extends into the screw-threaded bore 38 in the stepped cylindrical body 34 of the fuel distribution apparatus.
- fuel flows along the along the fuel line 16 as indicated in Figure 1 .
- the fuel line 16 terminates at one end of the fuel inlet channel 22.
- the fuel inlet channel 22 passes the fuel along its length to the annular inlet manifold 42 (see Figure 6 ).
- Fuel supplied by the fuel inlet channel 22 flows around the annular inlet manifold 42 until that manifold is full.
- Fuel then flows out of the manifold 42 under pressure, along the outlet fluid passageways 46 and into the annular outlet manifold 50. Again, fuel flows around the annular outlet manifold 50 and the tangential arrangement of the outlet fluid passageways 46 introduces a swirling motion to the fuel in the annular outlet manifold 50.
- the fuel swirls around the annular outlet manifold 50 in an anti-clockwise direction as shown in Figure 6 . Due to the swirl induced in the fluid, the fluid tends to flow around the outer wall of the annular outlet manifold 50 until that manifold is filled with fuel. At that point the fuel can enter the ports 52 and then flow along the fuel delivery tubes 54. Because the ports 52 are formed in the inner wall of the annular outlet manifold 50, because the fuel is swirling around the outlet manifold being pushed towards the outer wall of the manifold 50 and because the path that the fuel must take on entry into the ports and along the fuel delivery tubes is at a different swirl angle, the apparatus ensures that there is an even distribution of fuel between the three fuel delivery tubes 54. That means that fuel is evenly distributed to the nozzle 54 which reduces the perpensity for hot spots to occur in the combustion chamber 20.
- the fuel delivery tubes 54 follow a helical path which is travelling in the opposite rotational direction to the rotational direction imparted to fuel travelling around the annular outlet manifold 50 by the orientation of the outlet fluid passageways 46.
- fuel is arranged to flow in anticlockwise direction around the annular outlet manifold 50 and fuel then flows in a clockwise direction in the fuel delivery tubes 54. This change in direction effects more even fuel distribution between the tubes.
- the orientation of the port on the inner wall of the annular outlet manifold 50 ensures that the annular outlet manifold is more fully pressurised with fuel before fuel enters the ports 52. This, also, facilitates more even fuel distribution between the fuel delivery tubes 54.
- the fuel that travels along the fuel delivery tubes 54 emerges into the nozzle head 32 to be mixed with air prior to ignition in the combustion chamber 20.
- fluid passageways and three fuel delivery tubes are shown, an alternative plural number of each may be used where appropriate. It is preferable that the tubes and/or passageways are regularly angularly spaced around the manifolds. Also, a two to one relationship between passageways and tubes is preferable but not essential.

Description
- The invention relates to a fuel distribution apparatus, particularly but not exclusively limited to a fuel distribution apparatus for use in a jet engine.
- Conventional fuel injectors on many jet engines comprise a fuel injector mounted on an outer casing with fuel fed through an internal passage into a gallery that exits a nozzle to mix with swirled air for subsequent ignition. The fuel is merely sprayed into the swirling air.
- In some engines the use of a conventional air spray burner is not possible due to space constraints. Some small engines use vaporisers instead of air spray burners as a means of introducing fuel into the combustion chamber. Such vaporisers are not always appropriate and an alternative method for introducing fuel is required.
- In any such apparatus it is important that an even fuel spray in the combustion chamber is achieved to reduce the risk of uneven burning which can affect engine efficiency and introduce hot streaks or hot spots on the combustor walls.
-
WO 000070 - It is an object of the invention to provide an improved fuel distribution apparatus.
- According to one aspect of the invention there is provided a fuel distribution apparatus as set forth in claim 1.
- The change in the swirl angle between the fuel entering the outlet manifold and exiting the manifold to enter the fuel delivery tubes ensures a more even fuel distribution to all of the fuel delivery tubes.
- Preferably the fuel delivery tubes extend from the outlet manifold at an angle different to the swirl angle of fuel in the outlet manifold.
- The fuel delivery tubes extend from the outlet manifold in a different direction to the first swirl direction. The fuel delivery tubes may extend axially, parallel with the axis of the annular outlet manifold.
- Further preferred features of the invention are set out in the claims appended hereto.
- Preferably there is provided a fuel distribution apparatus comprising a body defining an inlet for receiving fuel, an inlet manifold having a plurality of outlet fluid passageways extending therefrom to an annular outlet manifold, the outlet fluid passageways being arranged to direct fluid into the annular outlet manifold in such a way as to cause the fluid to flow substantially circumferentially of the manifold, the manifold having a plurality of fluid exit ports formed in the radially inner wall thereof to allow fluid in the manifold to exit the manifold.
- In that way, the circumferential flow of fluid tends to push the fluid outwardly against the outer wall of the manifold and the manifold tends to fill with fluid before any fluid enters the exit ports.
- A fuel distribution apparatus in accordance with the invention will now be described in detail by way of example and with reference to the accompanying drawings, in which:
-
Figure 1 is a schematic cross-section of part of a combustion system of a jet engine showing a fuel distribution apparatus in accordance with the invention; -
Figure 2 is an enlarged sectional view of part of the combustion system showing part of the fuel distribution apparatus in accordance with the invention; -
Figure 3 is a schematic perspective view of the fuel distribution apparatus inFigures 1 and2 , looking from the front and one side; -
Figure 4 is a schematic perspective view of the fuel distribution apparatus ofFigure 3 looking from the rear and said one side; -
Figure 5 is a schematic side elevation of the fuel distribution apparatus shown inFigures 3 and4 ; -
Figure 6 is a view similar toFigure 3 shown to a larger scale with the extraneous material of the body of the fuel distribution apparatus removed for clarity; -
Figure 7 is a view from the rear and said one side of the fuel distribution apparatus ofFigure 6 , again with the body material removed for clarity. - In
Figure1 part of thecombustion system 10 of a jet engine is shown incorporating a fluid distribution apparatus indicated generally at 12 in accordance with the invention. - The
combustion system 10 comprises acasing 14 with a fuel line 16 (shown schematically) running from a fuel supply (not shown) to thefuel distribution apparatus 12. Thecasing 14 has aflat mounting surface 18 formed on the inside surface thereon facing acombustion chamber 20. Thefuel line 16 terminates and is in fluid communication withfuel inlet channel 22 drilled from themounting surface 18 into the inner part of thecasing 14. - The
mounting surface 18 also has anannular channel 24 machined into the surface, part of which is coincident with the point at which thefuel inlet channel 22 emerges from the body of thecasing 14. Furthermore, themounting surface 18 has a screw-threadedbore 26 formed concentrically with theannular channel 24. - The
fuel distribution apparatus 12 comprises amanifold head 28, a waistedportion 30 and anozzle head 32. - The
manifold head 28 comprises a steppedcylindrical body 34 having a substantiallyflat face 36 at one end for arrangement against themounting surface 18. A series of channels and passageways are machined into the surface of theface 36 so that when theface 36 is mounted against themounting surface 18, those channels form closed fluid passageways. - A screw-threaded
bore 38 is formed centrally of the steppedcylindrical body 34. The bore is substantially the same diameter as the screw-threaded bore in themounting surface 18 and is arranged co-axially therewith when thefuel distribution apparatus 12 is mounted on themounting surface 18. - Formed concentrically with the screw-threaded bore, an annular
inlet manifold channel 40 surrounds the screw threadedbore 38. The annularinlet manifold channel 40 has the same diameter as theannular channel 24 formed in themounting surface 18. Thus, when thefuel distribution apparatus 12 is mounted on themounting surface 18, theannular channel 24 and the annularinlet manifold channel 40 overlay one another so as to define anannular inlet manifold 42. - In
Figures 3-7 the channels formed in themounting surface 18 and themanifold head 28 are shown in negative form. In other words, what is shown inFigures 3-7 are the spaces defined within the fuel distribution apparatus. - Six
straight channels 44 are formed in theflat face 36 of the steppedcylindrical body 34. Thechannels 44 extend from the annularinlet manifold channel 40 substantially tangentially relative thereto. The channels are arranged at regular 60° degree intervals around the circumference of the annularinlet manifold channel 40. When closed off by themounting surface 18 of thecasing 14, thechannels 44 formoutlet fluid passageways 46. - An annular
outlet manifold channel 48 is formed concentrically with the annularinlet manifold channel 40 in theflat face 36 of the steppedcylindrical body 34. Again, when thechannel 48 is closed off by themounting surface 18 of thecasing 14, the annularoutlet manifold channel 48 forms anannular outlet manifold 50. The outer ends of theoutlet fluid passageways 46 open into theannular outlet manifold 50. Thus, theannular inlet manifold 42 and theannular outlet manifold 50 are connected together in fluid communication by means of theoutlet fluid passageways 46. The openings of theoutlet fluid passageways 46 are in the inner wall of theannular outlet manifold 50. Threeports 52 are formed in the inner wall of theannular outlet manifold 50. The ports are regularly angularly spaced at 120° degrees relative to each other. Theports 52 are respectively arranged between pairs ofoutlet fluid passageways 46. - The
ports 52 act as an entry for respectivefluid delivery tubes 54 which extend from theports 52 at one end thereof in a substantially helical fashion around the waistedportion 30 into thenozzle head 32. This is best shown inFig.5 . - In the present application, the term helical shall be understood to mean the shape a line would assume if wound around a cylinder or cone.
- The
fuel delivery tubes 54 are arranged so that their ends in thenozzle head 32 extend at an approximately 45° degree angle relative to the axis of the device defined by the annular manifolds: - In order to assemble the fuel distribution apparatus onto the
mounting surface 18, a bolt (not shown) is screwed into the screw-threadedbore 26 in themounting surface 18 and thefuel distribution apparatus 12 is screwed on to the protruding bolt so that the bolt extends into the screw-threadedbore 38 in the steppedcylindrical body 34 of the fuel distribution apparatus. - In use, fuel flows along the along the
fuel line 16 as indicated inFigure 1 . Thefuel line 16 terminates at one end of thefuel inlet channel 22. Thefuel inlet channel 22 passes the fuel along its length to the annular inlet manifold 42 (seeFigure 6 ). Fuel supplied by thefuel inlet channel 22 flows around theannular inlet manifold 42 until that manifold is full. Fuel then flows out of the manifold 42 under pressure, along theoutlet fluid passageways 46 and into theannular outlet manifold 50. Again, fuel flows around theannular outlet manifold 50 and the tangential arrangement of theoutlet fluid passageways 46 introduces a swirling motion to the fuel in theannular outlet manifold 50. The fuel swirls around theannular outlet manifold 50 in an anti-clockwise direction as shown inFigure 6 . Due to the swirl induced in the fluid, the fluid tends to flow around the outer wall of theannular outlet manifold 50 until that manifold is filled with fuel. At that point the fuel can enter theports 52 and then flow along thefuel delivery tubes 54. Because theports 52 are formed in the inner wall of theannular outlet manifold 50, because the fuel is swirling around the outlet manifold being pushed towards the outer wall of the manifold 50 and because the path that the fuel must take on entry into the ports and along the fuel delivery tubes is at a different swirl angle, the apparatus ensures that there is an even distribution of fuel between the threefuel delivery tubes 54. That means that fuel is evenly distributed to thenozzle 54 which reduces the perpensity for hot spots to occur in thecombustion chamber 20. - As can be seen in
Figures 6 and7 , thefuel delivery tubes 54 follow a helical path which is travelling in the opposite rotational direction to the rotational direction imparted to fuel travelling around theannular outlet manifold 50 by the orientation of theoutlet fluid passageways 46. Looking at theFigure 6 arrangement, fuel is arranged to flow in anticlockwise direction around theannular outlet manifold 50 and fuel then flows in a clockwise direction in thefuel delivery tubes 54. This change in direction effects more even fuel distribution between the tubes. - Also, the orientation of the port on the inner wall of the
annular outlet manifold 50 ensures that the annular outlet manifold is more fully pressurised with fuel before fuel enters theports 52. This, also, facilitates more even fuel distribution between thefuel delivery tubes 54. - The fuel that travels along the
fuel delivery tubes 54 emerges into thenozzle head 32 to be mixed with air prior to ignition in thecombustion chamber 20. - Although six fluid passageways and three fuel delivery tubes are shown, an alternative plural number of each may be used where appropriate. It is preferable that the tubes and/or passageways are regularly angularly spaced around the manifolds. Also, a two to one relationship between passageways and tubes is preferable but not essential.
